FIELD: hydraulic building, particularly for subterranean water protection against contamination by radioactive or toxic substances. SUBSTANCE: Permeable layer of antifiltering device for pond contaminant prevention from entering subterranean waters is formed of porous material. Milled glauconitic concentrate with glauconite content of 80% - 95% is used as porous material for radioactive or toxic particle binding. EFFECT: increased operating reliability. |
